Answer:

See below ↓↓

Step-by-step explanation:

a₁ refers to the first term of the sequence.

That is clearly : a₁ = 6

The formula for the nth term is :

aₙ = a₁rⁿ⁻¹
Common ratio (r) = quotient of consecutive terms
r = -12/6 = -2

Therefore, the nth term is :

aₙ = 6(-2)ⁿ⁻¹

aivan3 [116]

Answer:

90.8 m

Step-by-step explanation:

Pythagorean Theorem

A²+B²=C²

slant height = C

A = 19.6/2=9.8m

90.9 in to m = 2.3m

9.8²+B²=2.3²

B²=90.9²-2.3² = 8257.52

B= $\sqrt{8257.52}$ = 90.8

Which x value makes this equation true? Explain how you can tell

MrMuchimi

Answer:

b) x = 4

Explanation:

$2x^2 - x + 10 = 38$

collect variables

$2x^2 - x + 10 - 38 = 0$

simplify

$2x^2 - x - 28 = 0$

breakdown

$2x^2 -8x + 7x - 28 = 0$

factor out

$2x(x - 4) + 7(x - 4) = 0$

collect into groups

$(2x + 7)(x - 4) = 0$

set to zero

$2x + 7 = 0, x - 4 = 0$

relocate variable

$2x = -7, x = 4$

final solutions

$x = -3.5, x = 4$
